Abstract
We derive the neutral fermion excitation spectrum in the resonating-valence-bond state based on a fermion-boson field theory. It is formally shown that charge-e bosons are created upon doping while the neutral fermion excitation remains gapless, predicting a linear low-temperature specific heat C∝γT in the superconducting state. Bose condensation in doped samples leads to the observed superconductivity with true "off-diagonal long-range order."
